excavation
|
Archaeologists excavate sites so that they can find information and recover archaeological materials before they are destroyed by erosion, construction or changes in land-use.
Depending on how complicated and widespread the archaeological deposits are, excavation can be done by hand or with heavy machinery. Archaeologists may excavate a site in a number of ways; either by open area excavation, by digging a test pit or a trial trench. more ->

Prehistoric
|
About 500,000 BC to 42 AD
The Prehistoric period covers all the periods from the Palaeolithic to the end of the Iron Age. This is a time when people did not write anything down so there is no documentary evidence for archaeologists to look at. Instead, the archaeologists look at the material culture belonging to the people and the places where they lived for clues about their way of life.
The Prehistoric period is divided into the Early Prehistoric and Later Prehistoric. The Early Prehistoric period covers the Palaeolithic and Mesolithic periods. The Later Prehistoric period covers Neolithic, Bronze Age and Iron Age times. more ->

Iron Age
|
About 800 BC to 43 AD
The Iron Age comes after the Bronze Age and before the Roman period. It is a time when people developed the skills and knowledge to work and use iron, hence the name ‘Iron Age’ which is given to this period. Iron is a much tougher and more durable metal than bronze but it also requires more skill to make objects from it. People continued to use bronze during this period. more ->
